MyoWare 2 Muscle Sensor Basic Kit

The MyoWare® 2 Muscle Sensor Basic Kit is an Arduino-compatible, all-in-one electromyography (EMG) sensor kit that provides you with the bare minimum from the MyoWare 2 ecosystem to get started measuring and visualizing muscle activity. Simply snap on the MyoWare 2 LED Shield, add some EMG sensor pads, attach the sensor to a muscle group, and flex! The kit also includes a mini screwdriver for easy removal of shields, a USB A to C cable for recharging the 40mAh LiPo battery, and a MyoWare 2 Reference Cable to connect to large muscle groups

The MyoWare 2 Muscle Sensor included in this kit has been redesigned from the ground up with a new, easy-to-use, compact design and upgraded with the latest and greatest chipset, improving sensor performance and reliability. The sensor measures muscle activity through the electric potential of the muscle, commonly referred to as surface electromyography (EMG or sEMG for short). When your brain tells your muscle to flex, it sends an electrical signal to your muscle to start recruiting motor units (the bundles of muscle fibers that generate the force behind your muscles).

The harder you flex, the more motor units are recruited to generate greater muscle force. The greater the number of motor units, the more the electrical activity of your muscle increases. The MyoWare 2 Muscle Sensor analyzes the filtered and rectified electrical activity of a muscle. It outputs a signal (0-VIN volts, where VIN represents the voltage of the power source) that indicates the degree of muscle flexion. The innovative snap connector system eliminates the need to solder connections with the MyoWare 2 LED Shield. The blue 10-segment bar graph provides a visual representation of the measured signal. The more muscle activation measured, the higher the LEDs will go up the board.

This kit is designed to follow the standalone example featured in the MyoWare 2 Muscle Sensor Guide, eliminating the need for a microcontroller. Use it to gauge how hard you’re working a muscle during a workout, as a teaching tool, or add some myoelectric flair to your Halloween costume!
